Sensor housing and adjustable mast arm for a swivel lighting fixture

Abstract

A lighting fixture having a new and improved sensor housing and an adjustable mast arm. The sensor housing includes a top wall, a bottom wall, a back wall having a first lead aperture for establishing electrical and mechanical connections between a proximity sensor and a source of electrical power, a transition wall, a pair of side walls, and at least one drain aperture located between the transition wall and the bottom wall. A first partition wall is located between the bottom wall and the transition wall. The first partition wall extends between the pair of side walls to form a cavity including at least one drain aperture for preventing the accumulation of water in the sensor housing. An adjustable mast arm is connected between the base and the sensor housing. The adjustable mast arm includes a first pivot joint attached between the base and one end of the arm, a second pivot joint attached between the sensor housing and the other end of the arm, and a swivel joint located between the first and second pivot joints.
